Role of Dipolar and Nondipolar Components of the T Wave in Determining the T Wave Residuum in an Isolated Rabbit Heart Model
(Wiley Blackwell Publishing, Inc, 2004-03)
Introduction: Repolarization heterogeneity has been shown to constitute a substrate for malignant ventricular arrhythmias. Noninvasive measurement of abnormal repolarization through assessment of QT interval dispersion ...
Electrocardiographic markers of myocardial conduction and repolarization in boxer dogs
(2020-08-01)
Carvalho E.R, Zacché E., Fenerich M., Camacho A.A., Santos J.P. & Sousa M.G. 2020. Electrocardiographic markers of myocardial conduction and repolarization in Boxer dogs. Pesquisa Veterinária Brasileira 40(8):630-636. ...
Electrocardiography repolarization abnormalities are characteristic signs of acute chagasic cardiomyopathy.

Combined effects of exercise training and high doses of anabolic steroids on cardiac autonomic modulation and ventricular repolarization properties in rats
(Canadian Science Publishing, 2019-12-01)
Several studies have reported that high doses of synthetic anabolic androgenic steroids (AAS) can have serious negative effects on health, including the cardiovascular system. The aim of this study was to evaluate the ...
Spatio-temporal features of variability repolarization during acute myocardial ischemia
(Universidad Nacional de Río Negro, 2013)
Several studies have shown that dynamic variability of ventricular repolarization morphology is associated with an increased risk for developing ventricular arrhythmias. We evaluated beat-to bea ventricular repolarization ...
Beat-to-beat ventricular repolarization variability evaluated during acute myocardial ischemia
(Elsevier, 2013-08)
Experimental and clinical studies have shown that beat-to-beat variability of ventricular repolarization morphology, which can be measured by T-wave spectral variance (TSV) index based on the 2D-FFT, is associated with an ...
Global and Regional Ventricular Repolarization Study by Body Surface Potential Mapping in Patients with Left Bundle-Branch Block and Heart Failure Undergoing Cardiac Resynchronization Therapy
(WILEY-BLACKWELLMALDEN, 2012)
Background: The controversial effects promoted by cardiac resynchronization therapy (CRT) on the ventricular repolarization (VR) have motivated VR evaluation by body surface potential mapping (BSPM) in CRT patients. Methods: ...
Benign early repolarization versus malignant early abnormalities: Clinical-electrocardiographic distinction and genetic basis
(Via Medica, 2012-07-01)
In the great majority of cases the ECG pattern of early repolarization (ERP) is a benign phenomenon observed predominantly in teenagers, young adults, male athletes and the black race. the universally accepted criterion ...
Effects of 4-aminopyridine on pacemaker activity of frog sinus venosus
(1980)
The effects of low concentrations of 4-aminopyridine (4-AP) were studied on the frog sinus venosus by means of intracellular microelectrodes. 4-AP depressed spontaneous automaticity. This effect was not reversed by atropine. ...
